+
+ * a-calend-vms.adb, a-calend.adb:
+ Add a section on leap seconds control along with two entities used to

+ Add entity Leap_Seconds_Support to the list of global run-time variables
+ along with a comment on its usage and values.
+ (Gen_Adainit_Ada): Add code to generate the declaration and import of

+
+ * a-tags.adb:
+ (Get_HT_Link/Set_HT_Link): Updated to handle the additional level of
+ indirection added to the HT_Link component of the TSD. This is required
+ to statically allocate the TSD.
+
+ * a-tags.ads:
+ Minor reordering of the declarations in the private part. Required to
+ add a level of indirection to the contents of the TSD component HT_Link.
+ This is required to statically allocate the TSD.
+
+ * decl.c (gnat_to_gnu_entity) <object>: Do not exclude objects with
+ Is_Statically_Allocated set from constant objects.
+ Do not make exported constants created by the compiler volatile.
+ (gnat_to_gnu_param): Do not treat an IN parameter whose address is taken
+ as read-only.
+
+ * trans.c (Identifier_to_gnu): For constants, unshare initializers
+ before returning them.
+
+ * exp_disp.ads, exp_disp.adb (Building_Static_DT): Spec moved to the
+ public part of the package.
+ (Make_DT): Move HT_Link component out of the TSD record. For this
+ purpose Make_DT now declares a separate object that stores the
+ HT_Link value, and initializes the TSD component with the address
+ of this new object. The addition of this level of indirection is
+ required to statically allocate the TSD because the TSD cannot
+ have variable components.
+ (Expand_Interface_Conversion): Improve the expanded code.
+ (Expand_Interface_Thunk): Set Is_Thunk in the thunk entity.
+
+ * sem_disp.adb (Check_Dispatching_Operation): In case of a body
+ declaring a primitive operation ---allowed by RM 3.9.2 (13.e/2)---,
+ if we are building static dispatch tables then we must not generate
+ extra code to register the primitive because the dispatch table will
+ be built at the end of the library package; otherwise we notify that
+ we cannot build the static dispatch table.

+ * einfo.adb (Is_Thunk): New attribute applicable to subprograms. True
+ for thunks associated with interface types.
+
+ * einfo.ads: Improve documentatation of Is_Internal
+ (Is_Thunk): New attribute applicable to subprograms. True for thunks
+ associated with interface types.
+ Extensive comment fixes regarding flags that appear in all entities. The
+ documentation is now consistent for all such flags (there were a number
+ of errors in the documentation in this regard).
+
+ * exp_attr.adb (Expand_N_Attribute_Reference): Minor code cleanup.
+
+ * exp_ch6.adb (Make_Build_In_Place_Call_*): Return immediately if any
+ of these procedures are passed a function call that already has
+ build-in-place actuals (testing new flag
+ Is_Expanded_Build_In_Place_Call). Set the flag on the function call in
+ the case where processing continues.
+ (Expand_Call): If the call is generated from a thunk body then we
+ propagate the extra actuals associated with the accessibility
+ level of the access type actuals.
+
+ * sem_ch6.adb (Analyze_Subprogram_Body): Set the Protected_Formal field
+ of each extra formal of a protected operation to reference the
+ corresponding extra formal of the subprogram denoted by the
+ operation's Protected_Body_Subprogram.
+
+ * sinfo.ads, sinfo.adb (Is_Expanded_Build_In_Place_Call): New flag on
+ N_Function_Call nodes.

+
+ * exp_dbug.adb (Debug_Renaming_Declaration): Set Is_Internal on the

+ Initialize_Scalars is in effect.
+
+2007-09-26 Gary Dismukes <dismukes@adacore.com>
+
+ * freeze.adb (Freeze_Entity): Remove check for preelaborable
+ initialization of a full view. This is moved to
+ Analyze_Package_Specification.
+
+ * sem_ch7.adb (Analyze_Package_Specification): Add check for
+ preelaborable initialization of a full view in entity loop.
+ (Uninstall_Declarations): If entity is a use-visible compilation unit,
+ its child units are use-visible only if they are visible child units.
+
+ * sem_util.adb (Is_Preelaborable_Expression): New function to determine
+ whether an expression can be used within a type declaration that
+ requires preelaborable init.
+ (Check_Components): Replace inline code that does partial checking for
+ preelaborable default expressions with call to
+ Is_Preelaborable_Expression.
+ (Has_Preelaborable_Initialization): In the case of a generic actual
+ subtype, (that is, Is_Generic_Actual is True), return the result of
+ applying Has_Preelaborable_Initialization to the generic actual's base
+ type.
+
+2007-09-26 Hristian Kirtchev <kirtchev@adacore.com>
+
+ * g-calend.adb (Has_53_Weeks): Rename to Last_Year_Has_53_Weeks. Add a
+ call to Jan_1_Day _Of_Week to optimize its performance.
+ (Is_Leap): Move the routine to the scope of Week_In_Year.
+ (Jan_1_Day_Of_Week): New routine in Week_In_Year which calculates the
+ weekday on which January 1 falls of Year - 1 and Year + 1. This function
+ avoids calling Time_Of and Split, thus making it more efficent.
+ (Week_In_Year): Reimplemented in oder to follow ISO 8601.
+
+ * g-calend.ads (Week_In_Year): Change comment to reflect new
+ implementation.
+
+2007-09-26 Emmanuel Briot <briot@adacore.com>
+
+ * g-comlin.ads, g-comlin.adb (Command_Line_Configuration,
+ Command_Line): New types
+ (Define_Alias, Define_Prefix, Free): New subprograms. These provide
+ support for defining how switches can be grouped on a command line (as
+ is the case for -gnatw... for GNAT), and how simple switches can be
+ used as aliases for more complex switches (-gnatwa is same as
+ -gnatwbcef...)
+ (Set_Command_Line, Add_Switch, Remove_Switch): New subprogram
+ (Start, Current_*): New subprograms
+ Added support for parsing an array of strings in addition to the real
+ command line.
+ (Opt_Parser, Opt_Parser_Data): New type. As a result, some types had to
+ be moved from the body to the private part of the spec.
+ (*): All subprograms now have an extra parameter with default value to
+ specify which parser should be used. For backward compatibility, it
+ defaults to parsing the command line of the application. They were also
+ modified to properly handle cases where each of the argument does not
+ start at index 1 (which is always true for Ada.Command_Line, but not
+ when processing any Argument_List).
+ (Free): New subprogram
+ (Internal_Initialize_Option_Scan, Find_Longuest_Matching_Switch,
+ Argument): New subprograms
+ (Switch_Parameter_Type): New enum, which clarifies the code. The extra
+ special characters like ':', '=',... are now handled in a single place,
+ which makes the code more extensible eventually.
+ (Getopt, Full_Switch): When the switch was returned as part of the
+ special character '*', make sure it is prepended by the switch character
+ ('-' in general), so that the application knows whether "foo" or "-foo"
+ was specified on the command line.
+
+2007-09-26 Florian Villoing <villoing@adacore.com>
+
+ * g-dirope.adb (Remove_Dir): In case we are removing directories
+ recursively, make sure that if an exception is raised during the
+ processing, the current working directory is reset to its initial
+ value before propagating the exception.
+
+2007-09-26 Vincent Celier <celier@adacore.com>
+
+ * gnatbind.adb: If there are several ALI files specified and there is
+ a main program to bind, the first ALI is expected to contain the main
+ subprogram and the names of the binder generated files will be derived
+ from the first ALI file name.
+ (Gnatbind): Fix insertion character in invocation of Error_Msg

+ Remove components Default_Language and Config in Project_Tree_Data,
+ no longer used.
+
+ * prj-attr.adb: New attributes Required_Switches (<language>) in
+ packages Compiler and Binder.
+
+ * prj-nmsc.adb: Major rewrite of the processing of configuration
+ attributes for gprbuild. No impact on GNAT tools.
+
+ * prj-proc.ads, prj-proc.adb (Process_Project_Tree_Phase_2): No longer
+ process configuration attributes: this is done in Prj.Nmsc.Check.
+ (Recursive_Process): Make a full copy of packages inherited from project
+ being extended, instead of a shallow copy.
+ (Process_Project_Tree_Phase_1): New procedure
+ (Process_Project_Tree_Phase_1): New procedure
+ (Process): Implementation now uses the two new procedures
+
+ * prj-util.adb (Executable_Of): Get the suffix and the default suffix
+ from the project config, not the tree config that no longer exists.
